Rigid boxes are often seen in luxury packaging because of the weight, strength, and firmness conveyed by their structure. Dielines for rigid boxes, focus on the paper wrap that is applied to the exterior of the heavyweight chipboard (grey board) that give the boxes their structure. The interior of rigid boxes is often wrapped by a paper liner that carries a consistent look and feel throughout the unveiling experience. We recommend that you always print out the dieline to confirm dimensions, proportions, user experience, and that the structure is what you envisioned prior to applying artwork.
